Kodi malo otenthetsera ozizira adakumana ndi kugwedezeka kwa kutentha kwambiri panthawi yotenthetsera?

Zochitika ndi Zomwe Zimayambitsa Kugwedezeka Kwambiri ndi Kutentha Kwambiri
Kugwedezeka kwa kutentha kwambiri kumaonekera makamaka ngati kutentha kwa thupi lomaliza kukukwera mofulumira mkati mwa nthawi yochepa, zomwe zimapangitsa kuti pakhale kusintha kwakukulu kwa thupi. Zomwe zimayambitsa ndi zizindikiro zake ndi izi:
Zochitika Zachizolowezi: Mavuto nthawi zambiri amapezeka panthawi yosonkhanitsa bolodi la PCB, monga kusungunula mafunde ndi kusungunulanso mafunde. Mu kusungunula mafunde, kutentha koyambirira kumatha kufika pa 100°C, ndipo kutentha koyambirira kwa mafunde kumatha kufika pa 280°C kwakanthawi; mu malo oyambitsira kutentha koyambirira kwa kusungunula, kutentha koyambirira kumatha kupitirira 230°C.
Kuwonekera Mwachindunji: Kutentha kwakukulu mwadzidzidzi kungayambitse kuti zigawo za pulasitiki zotetezera kutentha za terminal zisungunuke, zipindike, ziphuphuke, kapena zisinthe mawonekedwe, ndipo zigawo zachitsulo zingasinthenso mawonekedwe ake chifukwa cha kutentha kwambiri.

Zoopsa Zazikulu Zomwe Zimabwera Chifukwa cha Kugwedezeka kwa Kutentha Kwambiri
Kugwedezeka kwa kutentha kwambiri sikungokhudza malo olumikizira okha, komanso kungayambitse mavuto angapo odalirika komanso otetezeka:
Kuchuluka kwa Kukana Kukhudzana ndi Mphamvu Zomwe Zimayambitsa Kutentha Kwambiri: Kutentha kwambiri kungayambitse kukhuthala kwa mphamvu pamalo olumikizirana a ma terminal ndi ma conductor, ndikupanga zigawo zoonda za oxide. Izi zitha kuwonjezera kwambiri kukana kukhudzana ndi mphamvu, ndipo kukhuthala kwa mphamvu kumabweretsa kutentha kwina, kupanga kuzungulira koopsa, komwe nthawi zina kumatha kuyambitsa moto.
Mphamvu Yochepa ya Makina: Kutentha kwambiri kumatha kupangitsa kuti zinthu zotanuka mkati mwa terminal zisamayende bwino komanso kuchepetsa mphamvu yolumikizirana, zomwe zimapangitsa kuti maulumikizidwe azisokonekera. Nthawi yomweyo, waya woteteza kutentha umatha kukalamba ndikusweka chifukwa cha kutentha kwambiri, zomwe zimachepetsa magwiridwe antchito a insulation.
Zotsatira pa Mphamvu Yonyamulira Mphamvu: Ngati malo otsekereza sanapangidwe bwino kapena kukonzedwa bwino (monga, chiŵerengero chosayenera cha kupsinjika), malo ake odutsa akhoza kuchepa, zomwe zimapangitsa kuti mphamvu yonyamulira mphamvu isakwane ndipo zimapangitsa kuti kutentha kukhale kosavuta pamene mphamvu ikuyenda.

Momwe Mungayankhire ndi Kuthetsa Kugwedezeka Kwambiri ndi Kutentha Kwambiri
Konzani Kusankha Zinthu: Sankhani zitsulo zomwe zimapirira kutentha kwambiri (monga mkuwa wotulutsa mpweya wambiri) ndi zinthu zopangidwa ndi utomoni.
Konzani Njira Yopangira Crimping: Yesetsani mosamala kuchuluka kwa crimping (chiŵerengero chovomerezeka cha terminal crimping 65%–75%, chiŵerengero cha conductor crimping 65%–80%).
Yang'anirani Bwino Njira Yokonzera Kutentha: Yang'anirani bwino kutentha ndi nthawi yomwe ili mu dera lotenthetsera, dera la mafunde, ndi dera lokwera kwambiri kuti mupewe kutentha kwambiri kwa nthawi yayitali. Tsatirani mosamala zenera la njira kuti mupewe kugwedezeka komwe kumachitika chifukwa cha kusintha kwa njira.
Limbikitsani Kuyang'anira Njira Yopangira Zinthu: Onetsetsani kuti pini yopangira zinthu yayikidwa bwino komanso kukula kwake; onetsetsani kuti malo ogwirira ntchito azitha kusungunuka; mukamayika zinthu, yeretsani bwino popanda kusuntha. Chotsani zotsatira zoyipa za zinthu zakunja pa malo ogwirira ntchito.
Tekinoloje Yolumikizira Njira Zina: Pazinthu zomwe zimafuna mphamvu yamagetsi komanso kutentha kwambiri, ganizirani kugwiritsa ntchito njira zolumikizira zamagetsi pogwiritsa ntchito ma frequency apamwamba komanso njira zina zolumikizira. Kulumikiza magetsi pogwiritsa ntchito ma frequency apamwamba kumalola mkuwa kusakanikirana ndi mamolekyulu, zomwe zimapangitsa kuti kukana kutentha kuchepe komanso kuwongolera kutentha kukhale bwino.
